Executive Summary
As part of the update to the Oklahoma Comprehensive Water Plan (OCWP), Camp Dresser
& McKee Inc. (CDM) prepared cost estimates to meet the drinking water infrastructure
needs for the next 50 years. While it is difficult to account for changes that may occur
within this extended period, it is necessary to evaluate, at least on the order-of-magnitude
level, the long range costs of providing potable water to the state's citizens, industries, and
farmers. The results of this study identify needs that individual providers may be unable to
meet without assistance. Meeting the drinking water needs for the next 50 years requires
support and funding assistance by various state and federal agencies.
In this study, project cost estimates are developed for a selection of existing water
providers. These costs are weighted, using a methodology similar to the U.S.
Environmental Protection Agency (EPA) system for determining national drinking water
infrastructure costs, to develop 13 regional cost estimates. The regional cost estimates
then are summed to provide a statewide cost estimate to meet drinking water needs for
the next 50 years.
This report is organized in three main sections. Section 1 serves as an introduction and a
summary of the study and includes abbreviated description of methodology and results.
Section 2 provides a detailed description of the methodology used to develop cost
estimates. This section includes lists of assumptions made, types of projects included or
excluded by the study, and sources used to develop projects and costs. Section 3
summarizes the regional and statewide cost estimates developed as part of this task.
Sections 4 through 16 provide details about each of the regional cost estimates. These
provide comprehensive information on selected providers, project lists used, and other
information used to develop the regional cost estimates.
1.1 OCWP Methodology
The OCWP methodology is similar to EPA's methodology presented in the report 2009
Drinking Water Infrastructure Needs Survey [DWINS] and Assessment: Fourth Report to
Congress. In this OCWP report, the term "2007 DWINS" is used to encompass the EPA
method, cost models, and results associated with the most recent survey. This task uses
the 13 regions, developed as part of other OCWP tasks, as the basis for developing cost
estimates. Figure 1-1 illustrates the OCWP method.

Equations 1-1 and 1-2 represent the summation equations used to calculate regional
costs.
Drinking Water Infrastructure Costs by Infrastructure Type and by Stratum =

A few of the key similarities between the OCWP and 2007 DWINS methodologies include
the following:
 The OCWP study used the same definition for small, medium, and large systems.
Categorization of water providers was based on projected 2060 population and project
size was based on projected 2060 total demands including retail, system losses, and
sales (more information on projections may be found in the Water Demand Forecast
Report available on the Oklahoma Water Resources Board [OWRB] website).

 The OCWP study used the same infrastructure type classification of distribution and
transmission, treatment, storage, source, and other. Generally, the definitions of each
category are the same between the 2007 DWINS and this study.
 The OCWP study used the same source water classification.
 The OCWP study used the same definition of project costs.
 The OCWP study used the same 2007 DWINS cost models except when EPA cost
models were unavailable.
 The OCWP study excluded all new reservoir projects similar to the 2007 DWINS. While
new reservoirs are a key part of meeting current and future water supply needs for
Oklahoma, the cost associated with developing new reservoirs depends significantly
on the local decisions. These decisions include whether to oversize for recreation,
aesthetic or environmental reasons, comparison between cost and reliability, and
location.
A few of the key differences between the OCWP and 2007 DWINS methodologies are
listed below:
 The OCWP study included all types of projects, not just those eligible for Drinking
Water State Revolving Fund (DWSRF) program. Examples of projects that were
included in the OCWP study but not in the 2007 DWINS are dam and reservoir
rehabilitation projects and projects specifically for new growth. Cost were split into
DWSRF eligible and non-eligible categories to help define the level of financial support
that could be potentially be sought by applicants for DWSRF loans administered by
OWRB.
 The OCWP study used a 50-year planning horizon compared to the 20-year planning
period for the 2007 DWINS.
 The OCWP study included projects that have been funded since the 2007 and 2008
surveys.
 The OCWP study developed project lists for selected providers while the 2007 DWINS
relied on projects submitted by each survey respondent.
Section 2 of this report provides more information on the methodology developed for
estimating drinking water infrastructure costs.
1.2 Regional Cost Estimates
Fifty-five of the 776 OCWP providers were selected for cost modeling. OCWP providers are
those included in the 2008 OCWP survey and for which water demand projections were
created. The selected providers, using the methodology outlined above and described in

detail in Section 2 of the report, were used to calculate the infrastructure costs of the
region and state.
Across the state, approximately $38 billion (in 2007 dollars) is required to meet the
drinking water infrastructure needs for the next 50 years. Figure 1-2 illustrates the total
drinking water infrastructure costs to meet the water needs until 2060 by region. The
Central region has the largest need, comprising over 31 percent of the state's need.
Middle Arkansas has the second largest need, comprising nearly 17 percent.
Table 1-1 illustrates the costs by size category and period. Small providers have the
largest overall drinking water infrastructure costs comprising nearly 46 percent of the
state's need. The largest infrastructure costs occur in the 2041 – 2060 period.

Section 2
Cost Estimating Approach
As part of the update to the OCWP, CDM prepared construction cost estimates to meet the
drinking water infrastructure needs for the next 50 years. This section provides detailed
information on the cost estimating methodology used in this study. This section begins
with a description of the EPA system for determining national drinking water infrastructure.
This subsection provides a foundation of knowledge, since the OCWP method is similar to
the EPA system. Next, this section describes the OCWP cost estimating approach. This
subsection includes a comparison to the EPA system, assumptions made, and sources of
information.
2.1 Background: EPA Drinking Water Infrastructure
Needs Assessment
The Safe Drinking Water Act requires EPA to periodically assess the needs of the nation's
water systems and use the results for allocating the DWSRF. Since the first survey was
completed in 1994/1995, EPA has made changes to improve and more accurately reflect
the 20-year costs of infrastructure needs.
The most recent EPA survey was completed in 2007. The report 2009 Drinking Water
Infrastructure Needs Survey and Assessment: Fourth Report to Congress presents the
methodology utilized by EPA to determine water needs and results from the survey. When
cost estimates were unavailable, EPA utilized cost models to estimate the project costs.
The report 2007 Drinking Water Infrastructure Needs Survey and Assessment: Modeling
the Cost of Infrastructure (cost models) documents these cost models. In this OCWP
report, the term "2007 DWINS" is used to reference the actual survey and all
documentation related specifically to this survey. The 2007 DWINS is the basis for the
OCWP cost estimating methodology.
To develop the water infrastructure costs, EPA sent a survey requesting drinking water
infrastructure needs information to all large providers and a statistically significant portion
of medium providers in each state. For small providers, EPA sent qualified personnel to
complete surveys at a statistically significant portion of small systems across the country.
The surveys collected project descriptions and cost estimates if available. Project costs
provided in the survey were adjusted to reflect January 2007 dollars. Projects are limited
to water system needs eligible for DWSRF program.
The cost models were primarily based on project costs received through the 2007 DWINS
survey. The cost models are appropriate for developing estimates of drinking water
infrastructure costs on a broad basis but should not be used to estimate the cost of
specific projects for individual systems for planning or financing purposes. The cost
models utilize minimal project information that is generally available, such as design
capacity and pipeline size. The cost models provide cost in January 2007 dollars.
Section 2
Cost Estimating Approach
 2-2
The description below focuses on the large, medium, and small community water systems
portion of the 2007 DWINS. EPA defined large systems as those serving more than
100,000 people, medium systems as those serving between 3,301 and 100,000 people,
and small systems as those serving 3,300 and fewer people. Community water systems
are defined as public water systems that serve at least 15 connections used by year-round
residents or that regularly serve at least 25 residents year-round.
To develop the state need for large water systems, EPA summed all eligible project costs
received. The simple method, shown in Equation 2-1, is possible since all large systems
were surveyed.
Large System Drinking Water Infrastructure Costs = Sum of Project Costs for
Systems Surveyed
Equation 2-1
EPA weighted the project costs included in the survey to determine the state need for
medium water systems. Equation 2-2 illustrates this method.
Medium System Drinking Water Infrastructure Costs = Number of Systems in
Stratum / Number of System Sampled * Sum of Project Costs for Systems Sampled
Equation 2-2
For small systems, EPA calculated a national average small system need and multiplied it
by the number of small providers in the state to determine the state's small water system
need. This approach is shown by Equation 2-3.
Small System Drinking Water Infrastructure Costs = Number of Systems in Stratum *
National Average Small System Need
Equation 2-3
Calculated project costs were multiplied by adjustment factors to account for regional
differences in construction costs.
Using the collected information, EPA created state level water needs. Then, EPA summed
the states' needs along with American Indian and Alaskan Native village water systems
and costs associated with proposed and recently promulgated regulations (developed
separately) to develop a national 20-year need. EPA presented the results by system size
and project type. Project types included distribution and transmission, treatment, storage,
source, and other.
2.2 OCWP Regional Cost Development
This section describes the details of the OCWP approach. It starts with a general
description and comparison with EPA's method. Then a discussion on how specific
providers were selected and sources of information is incorporated. Finally, this section
discusses how project lists were developed and provides a list of common assumptions
necessary to estimate costs.

2.2.1 OCWP Method: A General Overview
The OCWP method is similar to EPA's 2007 DWINS approach in many ways with only a few
key differences. This task used the 13 regions, developed as part of other OCWP tasks, as
the basis for developing cost estimates. Figure 2-1 illustrates the OCWP method. Several
of these topics are discussed in more detail in subsequent sections.

Similarities between the OCWP and 2007 DWINS methodologies include the following:
 The OCWP study used the same definition for small, medium and large systems.
Categorization of water providers was based on projected 2060 population and project
size is based on projected 2060 total demands including retail, system losses, and
sales (more information on projections may be found in the Water Demand Forecast
Report available on the Oklahoma Water Resources Board [OWRB] website).
 The OCWP study used the same infrastructure type classification of distribution and
transmission, treatment, storage, source and other. Generally, the definitions of each
category are the same between the 2007 DWINS and this study.
− The distribution and transmission category included all infrastructure required to
transport both raw and finished water. Typically raw water infrastructure was
called transmission while finished water infrastructure was labeled as distribution.
− The treatment category included all aspects of raw water treatment.
− The storage category included all finished water storage and only raw water
storage that are onsite and part of the treatment process.
− The source category included surface water intakes, wells, and spring collectors.
For the OCWP study, dams and reservoirs also were included as part of the source
water category.
Section 2
Cost Estimating Approach
 2-5
− The other category included all projects that do not meet one of the above
category definitions.
 The OCWP study used the same source water classification. Systems are categorized
as surface water if they have at least one source that is surface water or groundwater
under the direct influence (GWUDI) of surface water. Systems are categorized as
groundwater if they do not have a surface water or GWUDI source. If a water system
purchased water from another provider, it was grouped with the groundwater category
(EPA, in the 1995 assessment, found that purchased water suppliers costs more
closely resembled those of groundwater systems.) The SWDIS primary source
classification determined the water supply source type.
 The OCWP study used the same definition of project costs. Cost estimates assumed
complete construction costs including engineering and design, purchase of raw
materials and equipment, construction and installation labor, and final inspection.
Costs associated with system operation and maintenance (O&M) were not included.
 The OCWP study used the same 2007 DWINS cost models except where EPA cost
models are unavailable. Documentation on source and cost is provided in the OCWP
cost model table, located in Appendix A. One example of this is dam and reservoir
rehabilitation projects.
 The OCWP study excluded all new reservoir projects similar to the 2007 DWINS. While
new reservoirs are a key part of meeting current and future water supply needs for
Oklahoma, the cost associated with developing new reservoirs depends significantly
on the local decisions. These decisions include whether to oversize for recreation,
aesthetic or environmental reasons, comparison between cost and reliability, and
location.
Differences between the OCWP and 2007 DWINS methodologies are listed below:
 The OCWP study included all types of projects, not just those eligible for DWSRF
program. Examples of projects that were included in the OCWP study but not in the
2007 DWINS are dam and reservoir rehabilitation projects and projects specifically for
new growth.
 The OCWP study used a 50-year planning horizon compared to the 20-year planning
period for the 2007 DWINS.
 The OCWP study used several sources of information including:
− Oklahoma system specific information that was available from the 2007 DWINS.
− The 2008 OCWP survey, which collected information on existing infrastructure and
planned improvements. Cost information was not collected in this survey. More
information may be found in the Provider Survey Summary Report available on the
OWRB website.
Section 2
Cost Estimating Approach
 2-6
− Regional or provider water studies and master plans to supplement the above
resources.
 The OCWP project lists included drinking water infrastructure items necessary to meet
the 2060 projected annual average day water demands. This study did not evaluate
additional infrastructure that may be needed to meet the peak day demands on which
water projects typically are based. The 2007 DWINS did not distinguish between
annual average and peak day demands since participants provided project size.
 The OCWP study used incremental periods (2020, 2040, and 2060) to calculate costs.
 The OCWP study included projects that have been funded since the 2007 and 2008
surveys.
 The OCWP study developed project lists for selected providers while the 2007 DWINS
relied on projects submitted by each survey respondent. The process to select water
supply providers is discussed in Section 2.2.2 and more information is provided on the
project list development process in Section 2.2.3.
 The OCWP study did not determine Native American water demands separately,
determining instead that these needs are included through the various demand
categories encompassing the state of Oklahoma.
2.2.2 OCWP Method: Selecting Providers
Many factors were evaluated in order to select water supply providers for inclusion in the
OCWP study cost modeling. This section describes the selection process.
Starting with the OCWP water provider list for each region, providers were grouped by
stratum: large, medium, small, surface water, and groundwater. All large, surface water
providers were selected for cost modeling. There were no large, groundwater providers.
For other stratums, selecting at least one water supply provider in each stratum was the
goal. The quality and quantity of available data were the more important selection criteria.
Secondary criteria included choosing providers that were representative of each stratum
in population size served and were representative of the different counties within the
region. Figure 2-2 shows a decision tree that illustrates the selection process.
In most of the regions and in most of the stratums, there was at least one water service
provider suitable for cost modeling. Where there was not a suitable water service provider,
other methods were used to estimate costs. One example occurred in regions where there
was not a medium groundwater provider but there were medium purchased water
providers. In this situation, a neighboring region's medium groundwater stratum was used
for cost estimating. In this example, the modification was made at the regional level and
was reflected in the regional summation. Another example occurred in regions when there
was a suitable stratum provider except that this provider did not complete fully the
distribution piping section of the 2008 OCWP survey, which was necessary for project list
development. In this situation, a second water provider, similar in population size, was
Section 2
Cost Estimating Approach
 2-7
used to estimate existing distribution piping size, length and age. In this example, the
modification was made at the project list level and was reflected in the worksheet.
2.2.3 OCWP Method: Developing Project List
The next cost-modeling step was developing a project list for each selected provider. To
reduce the subjectivity of this step, a list of standard assumptions was developed and
used unless better information was available.
The first step in developing the provider's project list was to incorporate the 2007 DWINS
projects. The 2007 DWINS information provided project name and basic design
information required for cost modeling. When the 2007 DWINS projects contain cost
information, it was included in the OCWP study. In this study, all 2007 DWINS projects
occurred in the present to 2020 period.
Project development worksheets for surface water and groundwater sources were
developed. Information developed as part of other OCWP tasks and provided in the 2008
OCWP survey were used to complete this form. The OCWP standard assumptions
supplemented the available information. The worksheet provides a standard method for
Figure 2-2. Provider Selection Decision Tree
Section 2
Cost Estimating Approach
 2-8
estimating types of projects needed, project size, and project date. Examples of the
worksheets are in Appendix B.
In the absence of project descriptions, reasonable suppositions were made so that project
lists could be developed for individual water providers. The intent was not to make
detailed project lists but provide basic project information that enabled use of the 2007
DWINS cost models listed in Appendix A. The following items were typical of the
assumptions:
 If 2060 annual average day water demands exceed permitted water supplies, it is
assumed that the current source water will be utilized in the current proportions to
meet the 2060 demand. This task did not evaluate whether there is available supply
at the existing water sources as part of this task. Costs for wells followed EPA cost
model R1, which includes costs associated with siting, drilling, and developing a well
to completion. Costs for surface water intakes followed EPA cost model R7.
 Rehabilitation of existing major reservoirs was assumed to occur every 100 years. The
amount of storage for rehabilitation is based on the municipal water supply storage. If
unknown, the full normal pool storage was used. Reservoirs with no designated
municipal water supply storage were included in the study but show zero in the
rehabilitation column in the reservoir table in each individual region's section. The
project date is calculated from the construction date of the reservoir. The project has a
cost of $1,000 per AF of storage. This type of project was not included in the 2007
DWINS.
 EPA cost model X1 was used to determine infrastructure costs necessary to bring raw
water from the source to treatment system. To determine the parameters needed for
modeling, a single pipeline with a diameter sized to carry all of the needed capacity
and a distance of 25 miles (or 132,000 linear feet [LF]) was used. For surface water, it
was assumed that raw water pumps are required and costs for the pumps were
developed using EPA cost model R8. When a water treatment plant (WTP) project was
planned, the costs associated with raw water pumping was included in EPA cost model
T10 for the WTP project.
 For the purpose of this study, it was assumed that water treatment infrastructure
would be rehabilitated every 30 years. When water demand exceeds current treatment
capacity, additional treatment capacity to meet projected demand was included. In the
absence of more specific information, it was assumed that existing and new treatment
of surface water was in the form of a conventional filter plant. Costs for the
conventional treatment plant were determined using EPA cost model T10 for
rehabilitation/expansion of WTP. For treating groundwater, costs were determined
using EPA cost model T22 for groundwater chemical feed (no distinction between new
and rehabilitation). Other costs models were used as necessary to accommodate
different types of water treatment. If the existing treatment capacity was unknown, this
study included a rehabilitation/expansion project to meet the projected 2060 water
demands.
Section 2
Cost Estimating Approach
 2-9
 This study used EPA cost model P1 to account for finished water pumps.
 In order to estimate the needs associated with a growing distribution system
infrastructure, it was assumed that the distribution system total length grows in
proportion to population growth. Costs were calculated using EPA cost model M1 for
new distribution piping.
 It was assumed that the water system would have approximately 10 percent of their
treatment capacity in finished water storage. In the absence of more specific
information, this study used EPA cost model S2 for ground-level water storage. EPA
cost model S1 was used for elevated water storage.
 While the deterioration rate of transmission lines and distribution mains varies
considerably based on pipe material, soil conditions, and corrosiveness of the drinking
water, this study assumed that pipe would be replaced or rehabilitated every 75 years
or, stated in a different way, approximately 1.3 percent of the existing inventory would
be replaced or rehabilitated annually. Approximately 0.65 percent of pipe would be
replaced and costs determined using EPA cost model M1 for new pipe. The remaining
0.65 percent of pipe would be rehabilitated and costs determined using EPA cost
model M1 for rehabilitated pipe. This cost model included all components required for
distribution not limited to pipe, installation, hydrants, valves, and site work.
 Costs associated with purchasing water were not specifically developed. However,
water infrastructure needs associated with providers that use only purchased water
were included in the regional water needs through the use of the EPA finding that the
needs of providers that purchase water was similar to the needs of providers who
utilize groundwater.
2.2.4 OCWP Method: Summation of Projects
With completed project lists and costs, Equations 2-4 through 2-11 were used to calculate
regional and statewide drinking water infrastructure costs. The results are presented in
Section 3 of this report.

Section 3
Summary of Regional Drinking Water
Infrastructure Costs
Using the methodology outlined in Section 2, drinking water infrastructure cost estimates
were developed for each of the 13 regions. This section summarizes the costs. Details on
the individual regions can be found in Sections 4 through 16.
There are 776 OCWP providers in the state. OCWP providers are those included in the
2008 OCWP survey and for which water demand projections were created. Table 3-1
shows the number of water providers by stratum. Fifty-five providers were selected for cost
modeling. The selected providers' costs were extrapolated using the equations presented
in Section 2 to calculate the infrastructure costs of the region and state.

C Systems are classified as groundwater if they do not meet surface water definition above or if
they only purchase water.
D. From the time of the original survey, the number of providers has decreased due to normal
ODEQ review procedures.
Across the state, approximately $38 billion (in 2007 dollars) is required to meet the
drinking water infrastructure needs for the next 50 years. Figure 3-1 illustrates the total
drinking water infrastructure costs to meet the water needs until 2060 by region.
Table 3-2 identifies costs by region and period. The Central region has the largest need,
comprising over 31 percent of the state's need. Middle Arkansas has the second largest
need, comprising nearly 17 percent.

Using the project list worksheet, one surface water intake rehabilitation project for Colgate
Reservoir was included in the OCWP study. The 2007 DWINS identified seven well
rehabilitation projects.
Treatment Projects
Rehabilitation projects for the 1.2-mgd WTP in 2020 and 2060 were included in the OCWP
study. Additional, the 2007 DWINS identified a chlorination rehabilitation project.
Storage Projects
Rehabilitation projects totaling 0.73 MG of finished water storage were identified in the
2007 DWINS and were included in the OCWP study.
Distribution and Transmission Projects
Rehabilitation of one raw water transmission line with a capacity of 1.5 mgd was identified
using the project list worksheet.
Many distribution projects were identified in the project list worksheet and the 2007
DWINS. Projects included rehabilitation and replacement of existing pipelines and
installation of new pipelines to accommodate anticipated growth. Additionally, the 2007
DWINS identified some valves, flushing hydrants, and water meter replacement projects.

Executive Summary
As part of the update to the Oklahoma Comprehensive Water Plan (OCWP), Camp Dresser
& McKee Inc. (CDM) prepared cost estimates to meet the drinking water infrastructure
needs for the next 50 years. While it is difficult to account for changes that may occur
within this extended period, it is necessary to evaluate, at least on the order-of-magnitude
level, the long range costs of providing potable water to the state's citizens, industries, and
farmers. The results of this study identify needs that individual providers may be unable to
meet without assistance. Meeting the drinking water needs for the next 50 years requires
support and funding assistance by various state and federal agencies.
In this study, project cost estimates are developed for a selection of existing water
providers. These costs are weighted, using a methodology similar to the U.S.
Environmental Protection Agency (EPA) system for determining national drinking water
infrastructure costs, to develop 13 regional cost estimates. The regional cost estimates
then are summed to provide a statewide cost estimate to meet drinking water needs for
the next 50 years.
This report is organized in three main sections. Section 1 serves as an introduction and a
summary of the study and includes abbreviated description of methodology and results.
Section 2 provides a detailed description of the methodology used to develop cost
estimates. This section includes lists of assumptions made, types of projects included or
excluded by the study, and sources used to develop projects and costs. Section 3
summarizes the regional and statewide cost estimates developed as part of this task.
Sections 4 through 16 provide details about each of the regional cost estimates. These
provide comprehensive information on selected providers, project lists used, and other
information used to develop the regional cost estimates.
1.1 OCWP Methodology
The OCWP methodology is similar to EPA's methodology presented in the report 2009
Drinking Water Infrastructure Needs Survey [DWINS] and Assessment: Fourth Report to
Congress. In this OCWP report, the term "2007 DWINS" is used to encompass the EPA
method, cost models, and results associated with the most recent survey. This task uses
the 13 regions, developed as part of other OCWP tasks, as the basis for developing cost
estimates. Figure 1-1 illustrates the OCWP method.
Section 1
Executive Summary

Equations 1-1 and 1-2 represent the summation equations used to calculate regional
costs.
Drinking Water Infrastructure Costs by Infrastructure Type and by Stratum =
Number of Systems in Stratum / Number of System Sampled * Sum of Project Costs
for Systems Sampled by Infrastructure Type
Equation 1-1 Cost by Infrastructure Type and by Stratum (or Size)
Drinking Water Infrastructure Costs by Stratum = Sum of Drinking Water
Infrastructure Costs by Infrastructure Type and by Stratum
Equation 1-2 Cost by Region for Stratum
A few of the key similarities between the OCWP and 2007 DWINS methodologies include
the following:
 The OCWP study used the same definition for small, medium, and large systems.
Categorization of water providers was based on projected 2060 population and project
size was based on projected 2060 total demands including retail, system losses, and
sales (more information on projections may be found in the Water Demand Forecast
Report available on the Oklahoma Water Resources Board [OWRB] website).

 The OCWP study used the same infrastructure type classification of distribution and
transmission, treatment, storage, source, and other. Generally, the definitions of each
category are the same between the 2007 DWINS and this study.
 The OCWP study used the same source water classification.
 The OCWP study used the same definition of project costs.
 The OCWP study used the same 2007 DWINS cost models except when EPA cost
models were unavailable.
 The OCWP study excluded all new reservoir projects similar to the 2007 DWINS. While
new reservoirs are a key part of meeting current and future water supply needs for
Oklahoma, the cost associated with developing new reservoirs depends significantly
on the local decisions. These decisions include whether to oversize for recreation,
aesthetic or environmental reasons, comparison between cost and reliability, and
location.
A few of the key differences between the OCWP and 2007 DWINS methodologies are
listed below:
 The OCWP study included all types of projects, not just those eligible for Drinking
Water State Revolving Fund (DWSRF) program. Examples of projects that were
included in the OCWP study but not in the 2007 DWINS are dam and reservoir
rehabilitation projects and projects specifically for new growth. Cost were split into
DWSRF eligible and non-eligible categories to help define the level of financial support
that could be potentially be sought by applicants for DWSRF loans administered by
OWRB.
 The OCWP study used a 50-year planning horizon compared to the 20-year planning
period for the 2007 DWINS.
 The OCWP study included projects that have been funded since the 2007 and 2008
surveys.
 The OCWP study developed project lists for selected providers while the 2007 DWINS
relied on projects submitted by each survey respondent.
Section 2 of this report provides more information on the methodology developed for
estimating drinking water infrastructure costs.
1.2 Regional Cost Estimates
Fifty-five of the 776 OCWP providers were selected for cost modeling. OCWP providers are
those included in the 2008 OCWP survey and for which water demand projections were
created. The selected providers, using the methodology outlined above and described in
Section 1
Executive Summary
A 1-4
detail in Section 2 of the report, were used to calculate the infrastructure costs of the
region and state.
Across the state, approximately $38 billion (in 2007 dollars) is required to meet the
drinking water infrastructure needs for the next 50 years. Figure 1-2 illustrates the total
drinking water infrastructure costs to meet the water needs until 2060 by region. The
Central region has the largest need, comprising over 31 percent of the state's need.
Middle Arkansas has the second largest need, comprising nearly 17 percent.
Table 1-1 illustrates the costs by size category and period. Small providers have the
largest overall drinking water infrastructure costs comprising nearly 46 percent of the
state's need. The largest infrastructure costs occur in the 2041 – 2060 period.

Section 2
Cost Estimating Approach
As part of the update to the OCWP, CDM prepared construction cost estimates to meet the
drinking water infrastructure needs for the next 50 years. This section provides detailed
information on the cost estimating methodology used in this study. This section begins
with a description of the EPA system for determining national drinking water infrastructure.
This subsection provides a foundation of knowledge, since the OCWP method is similar to
the EPA system. Next, this section describes the OCWP cost estimating approach. This
subsection includes a comparison to the EPA system, assumptions made, and sources of
information.
2.1 Background: EPA Drinking Water Infrastructure
Needs Assessment
The Safe Drinking Water Act requires EPA to periodically assess the needs of the nation's
water systems and use the results for allocating the DWSRF. Since the first survey was
completed in 1994/1995, EPA has made changes to improve and more accurately reflect
the 20-year costs of infrastructure needs.
The most recent EPA survey was completed in 2007. The report 2009 Drinking Water
Infrastructure Needs Survey and Assessment: Fourth Report to Congress presents the
methodology utilized by EPA to determine water needs and results from the survey. When
cost estimates were unavailable, EPA utilized cost models to estimate the project costs.
The report 2007 Drinking Water Infrastructure Needs Survey and Assessment: Modeling
the Cost of Infrastructure (cost models) documents these cost models. In this OCWP
report, the term "2007 DWINS" is used to reference the actual survey and all
documentation related specifically to this survey. The 2007 DWINS is the basis for the
OCWP cost estimating methodology.
To develop the water infrastructure costs, EPA sent a survey requesting drinking water
infrastructure needs information to all large providers and a statistically significant portion
of medium providers in each state. For small providers, EPA sent qualified personnel to
complete surveys at a statistically significant portion of small systems across the country.
The surveys collected project descriptions and cost estimates if available. Project costs
provided in the survey were adjusted to reflect January 2007 dollars. Projects are limited
to water system needs eligible for DWSRF program.
The cost models were primarily based on project costs received through the 2007 DWINS
survey. The cost models are appropriate for developing estimates of drinking water
infrastructure costs on a broad basis but should not be used to estimate the cost of
specific projects for individual systems for planning or financing purposes. The cost
models utilize minimal project information that is generally available, such as design
capacity and pipeline size. The cost models provide cost in January 2007 dollars.
Section 2
Cost Estimating Approach
 2-2
The description below focuses on the large, medium, and small community water systems
portion of the 2007 DWINS. EPA defined large systems as those serving more than
100,000 people, medium systems as those serving between 3,301 and 100,000 people,
and small systems as those serving 3,300 and fewer people. Community water systems
are defined as public water systems that serve at least 15 connections used by year-round
residents or that regularly serve at least 25 residents year-round.
To develop the state need for large water systems, EPA summed all eligible project costs
received. The simple method, shown in Equation 2-1, is possible since all large systems
were surveyed.
Large System Drinking Water Infrastructure Costs = Sum of Project Costs for
Systems Surveyed
Equation 2-1
EPA weighted the project costs included in the survey to determine the state need for
medium water systems. Equation 2-2 illustrates this method.
Medium System Drinking Water Infrastructure Costs = Number of Systems in
Stratum / Number of System Sampled * Sum of Project Costs for Systems Sampled
Equation 2-2
For small systems, EPA calculated a national average small system need and multiplied it
by the number of small providers in the state to determine the state's small water system
need. This approach is shown by Equation 2-3.
Small System Drinking Water Infrastructure Costs = Number of Systems in Stratum *
National Average Small System Need
Equation 2-3
Calculated project costs were multiplied by adjustment factors to account for regional
differences in construction costs.
Using the collected information, EPA created state level water needs. Then, EPA summed
the states' needs along with American Indian and Alaskan Native village water systems
and costs associated with proposed and recently promulgated regulations (developed
separately) to develop a national 20-year need. EPA presented the results by system size
and project type. Project types included distribution and transmission, treatment, storage,
source, and other.
2.2 OCWP Regional Cost Development
This section describes the details of the OCWP approach. It starts with a general
description and comparison with EPA's method. Then a discussion on how specific
providers were selected and sources of information is incorporated. Finally, this section
discusses how project lists were developed and provides a list of common assumptions
necessary to estimate costs.

2.2.1 OCWP Method: A General Overview
The OCWP method is similar to EPA's 2007 DWINS approach in many ways with only a few
key differences. This task used the 13 regions, developed as part of other OCWP tasks, as
the basis for developing cost estimates. Figure 2-1 illustrates the OCWP method. Several
of these topics are discussed in more detail in subsequent sections.
Equations 2-4 through 2-11 are used to calculate regional and state level costs.

Similarities between the OCWP and 2007 DWINS methodologies include the following:
 The OCWP study used the same definition for small, medium and large systems.
Categorization of water providers was based on projected 2060 population and project
size is based on projected 2060 total demands including retail, system losses, and
sales (more information on projections may be found in the Water Demand Forecast
Report available on the Oklahoma Water Resources Board [OWRB] website).
 The OCWP study used the same infrastructure type classification of distribution and
transmission, treatment, storage, source and other. Generally, the definitions of each
category are the same between the 2007 DWINS and this study.
− The distribution and transmission category included all infrastructure required to
transport both raw and finished water. Typically raw water infrastructure was
called transmission while finished water infrastructure was labeled as distribution.
− The treatment category included all aspects of raw water treatment.
− The storage category included all finished water storage and only raw water
storage that are onsite and part of the treatment process.
− The source category included surface water intakes, wells, and spring collectors.
For the OCWP study, dams and reservoirs also were included as part of the source
water category.
Section 2
Cost Estimating Approach
 2-5
− The other category included all projects that do not meet one of the above
category definitions.
 The OCWP study used the same source water classification. Systems are categorized
as surface water if they have at least one source that is surface water or groundwater
under the direct influence (GWUDI) of surface water. Systems are categorized as
groundwater if they do not have a surface water or GWUDI source. If a water system
purchased water from another provider, it was grouped with the groundwater category
(EPA, in the 1995 assessment, found that purchased water suppliers costs more
closely resembled those of groundwater systems.) The SWDIS primary source
classification determined the water supply source type.
 The OCWP study used the same definition of project costs. Cost estimates assumed
complete construction costs including engineering and design, purchase of raw
materials and equipment, construction and installation labor, and final inspection.
Costs associated with system operation and maintenance (O&M) were not included.
 The OCWP study used the same 2007 DWINS cost models except where EPA cost
models are unavailable. Documentation on source and cost is provided in the OCWP
cost model table, located in Appendix A. One example of this is dam and reservoir
rehabilitation projects.
 The OCWP study excluded all new reservoir projects similar to the 2007 DWINS. While
new reservoirs are a key part of meeting current and future water supply needs for
Oklahoma, the cost associated with developing new reservoirs depends significantly
on the local decisions. These decisions include whether to oversize for recreation,
aesthetic or environmental reasons, comparison between cost and reliability, and
location.
Differences between the OCWP and 2007 DWINS methodologies are listed below:
 The OCWP study included all types of projects, not just those eligible for DWSRF
program. Examples of projects that were included in the OCWP study but not in the
2007 DWINS are dam and reservoir rehabilitation projects and projects specifically for
new growth.
 The OCWP study used a 50-year planning horizon compared to the 20-year planning
period for the 2007 DWINS.
 The OCWP study used several sources of information including:
− Oklahoma system specific information that was available from the 2007 DWINS.
− The 2008 OCWP survey, which collected information on existing infrastructure and
planned improvements. Cost information was not collected in this survey. More
information may be found in the Provider Survey Summary Report available on the
OWRB website.
Section 2
Cost Estimating Approach
 2-6
− Regional or provider water studies and master plans to supplement the above
resources.
 The OCWP project lists included drinking water infrastructure items necessary to meet
the 2060 projected annual average day water demands. This study did not evaluate
additional infrastructure that may be needed to meet the peak day demands on which
water projects typically are based. The 2007 DWINS did not distinguish between
annual average and peak day demands since participants provided project size.
 The OCWP study used incremental periods (2020, 2040, and 2060) to calculate costs.
 The OCWP study included projects that have been funded since the 2007 and 2008
surveys.
 The OCWP study developed project lists for selected providers while the 2007 DWINS
relied on projects submitted by each survey respondent. The process to select water
supply providers is discussed in Section 2.2.2 and more information is provided on the
project list development process in Section 2.2.3.
 The OCWP study did not determine Native American water demands separately,
determining instead that these needs are included through the various demand
categories encompassing the state of Oklahoma.
2.2.2 OCWP Method: Selecting Providers
Many factors were evaluated in order to select water supply providers for inclusion in the
OCWP study cost modeling. This section describes the selection process.
Starting with the OCWP water provider list for each region, providers were grouped by
stratum: large, medium, small, surface water, and groundwater. All large, surface water
providers were selected for cost modeling. There were no large, groundwater providers.
For other stratums, selecting at least one water supply provider in each stratum was the
goal. The quality and quantity of available data were the more important selection criteria.
Secondary criteria included choosing providers that were representative of each stratum
in population size served and were representative of the different counties within the
region. Figure 2-2 shows a decision tree that illustrates the selection process.
In most of the regions and in most of the stratums, there was at least one water service
provider suitable for cost modeling. Where there was not a suitable water service provider,
other methods were used to estimate costs. One example occurred in regions where there
was not a medium groundwater provider but there were medium purchased water
providers. In this situation, a neighboring region's medium groundwater stratum was used
for cost estimating. In this example, the modification was made at the regional level and
was reflected in the regional summation. Another example occurred in regions when there
was a suitable stratum provider except that this provider did not complete fully the
distribution piping section of the 2008 OCWP survey, which was necessary for project list
development. In this situation, a second water provider, similar in population size, was
Section 2
Cost Estimating Approach
 2-7
used to estimate existing distribution piping size, length and age. In this example, the
modification was made at the project list level and was reflected in the worksheet.
2.2.3 OCWP Method: Developing Project List
The next cost-modeling step was developing a project list for each selected provider. To
reduce the subjectivity of this step, a list of standard assumptions was developed and
used unless better information was available.
The first step in developing the provider's project list was to incorporate the 2007 DWINS
projects. The 2007 DWINS information provided project name and basic design
information required for cost modeling. When the 2007 DWINS projects contain cost
information, it was included in the OCWP study. In this study, all 2007 DWINS projects
occurred in the present to 2020 period.
Project development worksheets for surface water and groundwater sources were
developed. Information developed as part of other OCWP tasks and provided in the 2008
OCWP survey were used to complete this form. The OCWP standard assumptions
supplemented the available information. The worksheet provides a standard method for
Figure 2-2. Provider Selection Decision Tree
Section 2
Cost Estimating Approach
 2-8
estimating types of projects needed, project size, and project date. Examples of the
worksheets are in Appendix B.
In the absence of project descriptions, reasonable suppositions were made so that project
lists could be developed for individual water providers. The intent was not to make
detailed project lists but provide basic project information that enabled use of the 2007
DWINS cost models listed in Appendix A. The following items were typical of the
assumptions:
 If 2060 annual average day water demands exceed permitted water supplies, it is
assumed that the current source water will be utilized in the current proportions to
meet the 2060 demand. This task did not evaluate whether there is available supply
at the existing water sources as part of this task. Costs for wells followed EPA cost
model R1, which includes costs associated with siting, drilling, and developing a well
to completion. Costs for surface water intakes followed EPA cost model R7.
 Rehabilitation of existing major reservoirs was assumed to occur every 100 years. The
amount of storage for rehabilitation is based on the municipal water supply storage. If
unknown, the full normal pool storage was used. Reservoirs with no designated
municipal water supply storage were included in the study but show zero in the
rehabilitation column in the reservoir table in each individual region's section. The
project date is calculated from the construction date of the reservoir. The project has a
cost of $1,000 per AF of storage. This type of project was not included in the 2007
DWINS.
 EPA cost model X1 was used to determine infrastructure costs necessary to bring raw
water from the source to treatment system. To determine the parameters needed for
modeling, a single pipeline with a diameter sized to carry all of the needed capacity
and a distance of 25 miles (or 132,000 linear feet [LF]) was used. For surface water, it
was assumed that raw water pumps are required and costs for the pumps were
developed using EPA cost model R8. When a water treatment plant (WTP) project was
planned, the costs associated with raw water pumping was included in EPA cost model
T10 for the WTP project.
 For the purpose of this study, it was assumed that water treatment infrastructure
would be rehabilitated every 30 years. When water demand exceeds current treatment
capacity, additional treatment capacity to meet projected demand was included. In the
absence of more specific information, it was assumed that existing and new treatment
of surface water was in the form of a conventional filter plant. Costs for the
conventional treatment plant were determined using EPA cost model T10 for
rehabilitation/expansion of WTP. For treating groundwater, costs were determined
using EPA cost model T22 for groundwater chemical feed (no distinction between new
and rehabilitation). Other costs models were used as necessary to accommodate
different types of water treatment. If the existing treatment capacity was unknown, this
study included a rehabilitation/expansion project to meet the projected 2060 water
demands.
Section 2
Cost Estimating Approach
 2-9
 This study used EPA cost model P1 to account for finished water pumps.
 In order to estimate the needs associated with a growing distribution system
infrastructure, it was assumed that the distribution system total length grows in
proportion to population growth. Costs were calculated using EPA cost model M1 for
new distribution piping.
 It was assumed that the water system would have approximately 10 percent of their
treatment capacity in finished water storage. In the absence of more specific
information, this study used EPA cost model S2 for ground-level water storage. EPA
cost model S1 was used for elevated water storage.
 While the deterioration rate of transmission lines and distribution mains varies
considerably based on pipe material, soil conditions, and corrosiveness of the drinking
water, this study assumed that pipe would be replaced or rehabilitated every 75 years
or, stated in a different way, approximately 1.3 percent of the existing inventory would
be replaced or rehabilitated annually. Approximately 0.65 percent of pipe would be
replaced and costs determined using EPA cost model M1 for new pipe. The remaining
0.65 percent of pipe would be rehabilitated and costs determined using EPA cost
model M1 for rehabilitated pipe. This cost model included all components required for
distribution not limited to pipe, installation, hydrants, valves, and site work.
 Costs associated with purchasing water were not specifically developed. However,
water infrastructure needs associated with providers that use only purchased water
were included in the regional water needs through the use of the EPA finding that the
needs of providers that purchase water was similar to the needs of providers who
utilize groundwater.
2.2.4 OCWP Method: Summation of Projects
With completed project lists and costs, Equations 2-4 through 2-11 were used to calculate
regional and statewide drinking water infrastructure costs. The results are presented in
Section 3 of this report.
A 3-1
Section 3
Summary of Regional Drinking Water
Infrastructure Costs
Using the methodology outlined in Section 2, drinking water infrastructure cost estimates
were developed for each of the 13 regions. This section summarizes the costs. Details on
the individual regions can be found in Sections 4 through 16.
There are 776 OCWP providers in the state. OCWP providers are those included in the
2008 OCWP survey and for which water demand projections were created. Table 3-1
shows the number of water providers by stratum. Fifty-five providers were selected for cost
modeling. The selected providers' costs were extrapolated using the equations presented
in Section 2 to calculate the infrastructure costs of the region and state.

B Systems are classified as surface water if they have at least one source that is surface water
or groundwater under the direct influence of surface water.
C Systems are classified as groundwater if they do not meet surface water definition above or if
they only purchase water.
D. From the time of the original survey, the number of providers has decreased due to normal
ODEQ review procedures.
Across the state, approximately $38 billion (in 2007 dollars) is required to meet the
drinking water infrastructure needs for the next 50 years. Figure 3-1 illustrates the total
drinking water infrastructure costs to meet the water needs until 2060 by region.
Table 3-2 identifies costs by region and period. The Central region has the largest need,
comprising over 31 percent of the state's need. Middle Arkansas has the second largest
need, comprising nearly 17 percent.

Beaver-Cache Regional Infrastructure Costs
This section provides some general information about the Beaver-Cache region, identifies
water providers selected for modeling and their project lists, and provides a cost summary
for this region.
4.1 Beaver-Cache –Regional Description
The Beaver-Cache Watershed Planning Region is a 3,288-square-mile area in the
southwest quadrant of Oklahoma, spanning from the southern portion of Caddo County in
the north to the Red River on the south, and including all or portions of Tillman,
Comanche, Cotton, Grady, Stephens, Kiowa, and Jefferson Counties. There are 31 OCWP
providers in this region. OCWP providers are those included in the 2008 OCWP survey and
for which water demand projections were created. Table 4-1 shows the number of Beaver-
Cache water providers by stratum.
Table 4-1. Beaver-Cache Region – Number of OCWP Providers by Stratum

A Population classification was based on 2060 projection (see Water Demand Forecast Report for more
details on projections).
B Systems were classified as surface water if they have at least one source that is surface water or
groundwater under the direct influence of surface water.
C Systems were classified as groundwater if they do not meet surface water definition or if their primary
source of water is purchased from another provider.
